<p>PROBLEM TO BE SOLVED: To provide a technique with which a shape of a building is measured, three-dimensional data thereof is stored in a verifiable state, and inner structure can be verified with the three-dimensional model even after completion of the building.SOLUTION: When a building is constructed by multiple processes, the building at respective processes is optically scanned with laser beams, three-dimensional data is obtained based on reflected light from the building, data for verification of the three-dimensional data is associated with the three-dimensional data, and the three-dimensional data of the respective processes is stored. Then, the three-dimensional data of at least two processes of the respective processes is output in the coordinate system having the same original point to determine validity of the respective three-dimensional data based on the data for verification.</p> |
